How Long to Grill Corn on the Cob in Foil?

To grill corn on the cob in foil, you will typically cook it for about 15 to 20 minutes over medium heat. Wrapping the corn tightly in foil ensures even cooking while keeping the corn juicy and tender. However, the exact grilling time can depend on the size of the corn cobs and the heat of your grill.

Ingredients Needed

  • Fresh corn on the cob (husked and cleaned)
  • Butter (optional)
  • Salt (to taste)
  • Black pepper (to taste)
  • Additional seasonings (optional such as garlic powder, paprika, or cheese)
  • Aluminum foil

Essential Equipment

  • Grill (charcoal or gas)
  • Aluminum foil
  • Grill tongs
  • Knife (for cutting corn if necessary)
  • Measuring spoons (for seasonings)

Preparation Steps

  1. Preheat the Grill: Begin by preheating your grill to medium heat, around 350°F to 400°F. This ensures that the corn cooks evenly.
  2. Prepare the Corn: Husk the corn, removing all the green leaves and silks. Rinse the corn under cold water to remove any remaining silk.
  3. Season the Corn: If desired, spread butter over the corn and sprinkle with salt, pepper, and any other seasonings you prefer. This step enhances the flavor remarkably.
  4. Wrap in Foil: Take a piece of aluminum foil, about 12×12 inches, and place the seasoned corn in the center. Fold the foil over the corn tightly to create a sealed packet. Make sure there are no openings where steam can escape.
  5. Grill the Corn: Place the foil-wrapped corn directly on the grill grates. Close the grill lid to maintain a consistent temperature.
  6. Check for Doneness: Grill the corn for 15 to 20 minutes. Halfway through the cooking time, you can turn the packets over to ensure even cooking.
  7. Remove and Serve: After cooking, carefully open the foil packets, as steam can escape. Let the corn cool for a minute, then serve with additional butter or toppings as desired.

Best Practices for Grilling Corn in Foil

Choosing the Right Corn

Fresh, sweet corn is essential for achieving optimal flavor. Look for ears that are bright green with tightly wrapped husks and plump kernels. Avoid any corn with dry, brown husks or exposed kernels.

Testing for Doneness

Checking for doneness is crucial to avoid overcooking. Corn is done when the kernels are tender and can be easily pierced with a fork. If you’re unsure, you can carefully open one packet and test the corn before removing all of them from the grill.

Flavor Variation Suggestions

  • Mexican Street Corn Style: Brush with mayo and sprinkle with cotija cheese, lime juice, and chili powder after grilling.
  • Herb Garlic Corn: Mix softened butter with minced garlic and chopped parsley for an herb-infused butter.
  • Spicy BBQ Corn: Use BBQ sauce before wrapping the corn for a smoky flavor.

Common Mistakes to Avoid

Using Old Corn

Older corn can be tough and lack flavor. Always try to use fresh corn for the best grilling experience.

Poorly Sealing the Foil

Failing to seal the foil can lead to dry corn. Make sure the packet is tightly sealed to trap steam and moisture.

Not Preheating the Grill

Grilling on a cool grill can result in uneven cooking. Always preheat your grill to ensure consistent cooking results.

Storage and Reheating Tips

If you have leftover grilled corn on the cob, here are some storage and reheating techniques:

  • Storage: Wrap leftover corn in plastic wrap or aluminum foil and store in an airtight container in the refrigerator for up to three days.
  • Reheating: Reheat corn by placing it back on the grill for a few minutes, or heat it in the microwave wrapped in a damp paper towel for moisture.

Creative Serving Suggestions

Grilled corn is versatile and can be served in many ways:

  • As a side dish to grilled meats or fish.
  • Cut off the cob and mixed into salads for added crunch.
  • In summer corn chowder or mixed vegetable dishes.

Grilling Corn with the Husk On

Another option is grilling corn with the husk still attached. This method provides a more earthy flavor and keeps the corn moist. To do this:

  1. Soak the corn (still in its husk) in water for about 20 minutes to prevent burning.
  2. Shake off excess water and place the corn directly on the grill.
  3. Grill for 20-25 minutes, turning occasionally. You’ll know it’s done when the husks are charred.

Conclusion

Grilling corn on the cob in foil is an easy and delicious way to enjoy this summer staple. By following the steps outlined above, you can master the art of grilling corn, ensuring a flavorful result every time. Remember that the cooking time may vary slightly based on your grill’s heat and the size of the corn, so keep an eye on it as it cooks.
